Recharging connector for portable LP (liquefied petroleum) gas cylinders

Abstract

A connector ( 1 ) is provided between both portable LP gas storing cylinders when transferring and charging LP gas from this to that. One retainer ( 6 ) for a supplying LP gas cylinder ( 2 ) is positioned on an upper surface of a connector main body ( 5 ) which houses a flow passage opening and closing valve ( 4 ). The other retainer ( 7 ) for a receiving LP gas cylinder ( 3 ) is arranged on a lower surface of the connector main body ( 5 ). The upper surface of the connector main body ( 5 ) is opened at a mid portion of the one retainer ( 6 ) to provide an LP gas receiving inlet ( 14 ), which communicates with an LP gas taking outlet ( 23 ) provided by opening the lower surface of the connector main body ( 5 ) at a mid portion of the other retainer ( 7 ) through the flow passage opening and closing valve ( 4 ).

What is claimed is:  
     
       1. A recharging connector having a main body with two ends for transferring LP gas between a pair of portable LP gas cylinders each having a shut-off valve for preventing passage of gas, said recharging connector adapted to accommodate an LP gas cylinder at each end and open a shut-off valve of an LP gas cylinder when mounted at one end thereon, wherein 
       one retainer ( 6 ) for a supplying LP gas cylinder ( 2 ) is positioned on an upper surface of said connector main body ( 5 ) which houses a flow passage and a flow passage opening and closing valve ( 4 ) and another retainer ( 7 ) for a receiving LP gas cylinder ( 3 ) is arranged on a lower surface of said connector main body ( 5 ), said recharging connector arranged to connect the retainers generally along the same axis, the upper surface of the connector main body ( 5 ) being opened at a mid portion of the one retainer ( 6 ) to provide an LP gas receiving inlet ( 14 ), which communicates with an LP gas taking outlet ( 23 ) provided by opening the lower surface of the connector main body ( 5 ) at a mid portion of the other retainer ( 7 ) through the flow passage opening and closing valve ( 4 ).
